code: def sdm_monomial_lcm(A, B):
      r"""
      Return the "least common multiple" of ``A`` and ``B``.
  
      IF `A = M e_j` and `B = N e_j`, where `M` and `N` are polynomial monomials,
      this returns `\lcm(M, N) e_j`. Note that ``A`` and ``B`` involve distinct
      monomials.
  
      Otherwise the result is undefined.
